L'Abbaye Lutece
www.paris-fractional-ownership.com/abbaye.php

This rare Paris apartment, located next to Notre Dame, on the beautiful historic 'Ile de la Cite' has two bedrooms and two bathrooms, and entirely faces the inner courtyard of a quiet medieval building where Monks once chanted every day. One of the building's walls was once the protecting wall of the city that separated the Island (then called Lutece) from the rest of the world.
